SAMUEL BLOOD, OF MANCHESTER, NEW HAMPSHIRE.

i-M PROVEMENT IN SPINNING-FL'ILE'RS.

To all whom, it may concern:

Be it known that I, SAMUEL BLooD, otManchester,in the countyofHillsborough and State of New Hampshire, have invented a new anduseful Improvement in Bobbin-Presses; and

I do hereby declare that the following is a full and exact descriptionthereof, reference being bad to the accompanying drawings, and to theletters of reference marked thereon, where similar parts'are representedby the same let- 'full size, spring and hinge joint left off; Fig.

6, a plan of-presserwithontjoint and spring.

The object of my invention is to produce a cheap removable presser forwinding the roving upon any kind of bobbins, so constructed as to bemore useful than other pressers now in use designed for the samepurpose.

-To enable others skilled in the art to make and use my invention, Iwill p'roceed to describe its mode of construction and the manner of itsoperation. I In the first place I make a clamp, (1, Figs. 1, 2, 3, 4, oftwo parts m m, Figs. 3, 4, 6, of brass or other metal, the inside of amade to lit the flier a loosely, so that a will easily turnon c. Theparts or halves m m are then put together, and a hole drilled throughboth for the reception of boltf, Figs. 1, 2. One end of fis headed, andits opposite end is threaded and screws into in, Fig. 3, and thus bymeans off and'shoulder n, Fig. 6, m and m are held together, forming theclamp 0.. There is another hole drilled through (1, Figs. 1, 2, intowhich is inserted a swivel bolt or stud, with its head at b, Fig. 1.Into its opposite end at b, Fig. 2, which projects beyond a, as shown byb, Fig. 3, is a notch or mortise, into which is inserted one end of thepresser x. as shown at b, Fig. 2, :0 near I) having ashoulder to confineit in place, and being held in b by means ofia. rivet passing through I)and the flattened end ofw at b, Fig. 4, and there riveted, thus makingwith a: and b a hinge-joint at b, Figs. 1, 2, 3., 4, and by therevclutionofb in its bearings a revolving hinge-joint, for a purposehereinafter described.

From a, Figs. 1, 2, 3, I make aprojcction, j. to which is riveted oneend of spring i, Fig. 3..

i isa flattened spring. which is coiled around the flierarm or tube 0,Figs. 1., 2, several times, similar to the mainspring of a watch; and iat its other end is attached to the slotted segment Ii, Iiigs. l, 2, 3.

h isa thin piece of iron or segment of ahollow cylinder, reaching haliway around 0, with a slot running nearly its length, portions of whichare seen in Figs. 1, 2, 3, h being first made separate and confined inits place by 9, Fig. 1.

g is a screw that is let into 0, the head of 9 being large enough (seeFig l) to cover the width of It, and the barrel of 9 small enough topermit it to play freely through the slot in h. On loosing g, h may beslid along under the head ofg around '0 either way, and whentlie'desired amount of tension-on i has been attained g is screwed downinto 0, its head coming down on h, and 9 thus holds h and i at suchtension as the pressure of :0 upon its bobbin may require, and thus thepressure of as, may be regulated as from time to time is de' sired bytightening or loosening i, as described.

Whenever a bobbin is filled it must be removed from its spindle and anempty one placed thereon in its stead. In presses as heretoforeconstructed this removal has been difficult and somewhat troublesome,requiring both hands of the operative. To obviate this I haveconstructed the presser-arm a: with its swivel elbowjoint, as described,for the pur pose of readily throwing off the arm :0 from its bobbin whenfull in this'wayviz., by grasping cwith one hand and pressing the thumbon a'near f, Fig. 1, whereby w is relieved from its guides's" 8, Fig.2,when :rdrops by its own weight-into the position shown by the dottedlines ofac, Figs. 1, 2. The bobbin, thus released of its presser, isremoved and an.- otheris inserted in its place with the same hand, when:r is again returned to its former position upon the bobbin, ready foranother winding. All of this is readily performed with the same hand,while the other hand of the operative may be holding other bobbins orotherwise employed, causing a great saving of labor and time in thispart of the work.

On a ats and s, Fig. 2, I make two projections or guides to hold :0 inits proper place while the bobbin is being wound. The space between 5'and s, Fig. 2, is a little greater than I bin. By my arrangement thepresser-arm x,

the width of m, where it rests in this space toallow of aslightperpendicular mot-ion ofac on its bobbin, that m, by its shifting from sto s as the bobbin rises and falls, may adapt its delivery to the headof a bobbin and run its roving close to either head of the bobbin, so asto wind the entire band of the bobbin equally and evenly.

Through a, I make a small slot. through which 22 appears, as shown inFig. 2.

o is a pin set'permanently in c for the purpose of limiting therevolutionof a and of holding a in its proper place on c, and also forholding a from whirling around a, when w is dropped, as beforementioned. After constructing'a as described and adding thereto itsseveral parts, I proceed to balance or adjust my presser before placingit on its flier. I place the presser on a small spindle to seeif itsparts are equal in weightthatis to say, if the parts of the presser onthe several sides of the dotted lines k k, Figs. 1, 6, are of equalweight, so that the portion of a on'the left of k k, Fig. 1, shallexactly counterbalance the portion of a on the right of k 7:, Fig. 1,with the arm :0 extended upon its bobbin, as represented in Fig. 1. Ifthe parts of the presser on this line is is do .so balance, then, andnot till then, do I attach the presser to the flier. After putting thepresser upon its flier-tube, I again balance the presser and its tubewith the opposite tube or arm of the flier that the flier itself may beequipoised.

. Although thepresser, as shown in Fig. 6, is balanced perpendicularlyon line 70 k, as described, for experiment or test, yet the presser isalso balanced horizontally in actual use in its horizontal turning upontube 0, Fig. 1, uporr k k, which imaginary dotted line' is intended torepresent-the center line or the center itself of tube a. This heel (itmight be called) of a, Figs. 1. 2, that is always on the side of thetube opposite w, and thus always counterbalancing was w is removed fromthe center of its bobbin in the process of filling, is the'preciseparticular in which my presser differs from those permanent] y attachedto their fliers. The object of this balancing of the presser is toobviate the disturbance of the equilibrium of the flier caused in otherpressers by the pressers arm being removed from the'center of thebobblnsrevolution in process of filling the bobbeing drawn back as it fills thebobbin, is always kept balanced by the opposite side of the presser,which turns in a direction opposite to that of the arm at, the twoequipoised parts on the right and left of k k, Fig. 1, revolving aroundthe center line of tube 0, as before'described. thuspreserving alwaysthe equilibrium of the flier while the bobbin is being filled, a resultthat is believed never before to have been attained.

I contemplate the using of a spiral spring coiled around the flier tubeand attached to the presser in a manner similar tot, ifsuch aspringshall be found preferable to the one before described. The springrepresented in the drawings by letter i is made similar to awatchspring, as before described. and'coiled around itself severaltimes, every diameter of the different coils being of differentlengthsand the spring itself covering a space on couly equal to the width of2', as shown, Figs. 1, 2. 3; whereas by a spiral spring, I mean a springwith each coil surroundings, and each coil of the same diameter, windinglike the worm or thread of ascrew,thus.maki ng the s-pi ral spring tooccupy a space lengthwise of 0 equal to the several widths of the springcoiled'mult-iplied by the number of coils it makes around 0.

' Otheradvantages of my presser are that it can be more cheaply made andis put upon its flier at far less expense than presser-s that aresoldered or brazed to their fliers. is more readily repaired, and isless liable to bethrown off of its flier by the fliers revolution.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The revolving hinge-joint in the arm of a presser, ,for the purposesdescribed.

r 2. The guides ss for the arm at, constructed. substantially asdescribed, whether a: is used with or without the spring and jointedarm. 3. The combination of the jointed presserarm :0, the guides s s,the spring 2', with its ad justments, and the construction andapplication of the presser to itsflier, so that the presser shall alwaysbe equipoised in theact of windin g, substantially as and for thepurposes herein set forth.
